Understanding Pelvic Torsion: The Inflare / Outflare Dynamic
When we assess pelvic dysfunction, we are not looking for โbones out of place.โ
We are identifying a 3-dimensional torsional pattern that alters load transfer through the entire pelvic ring.
This diagram illustrates a common osteopathic presentation:
๐ด Dorsal Inflare
The tuber sacrale moves medially and slightly caudally.
This increases compression through the dorsal sacroiliac ligament and reduces the functional diameter of the dorsal pelvic outlet.
Perineal and pelvic floor tissues often become congested or reactive.
๐ต Ventral Outflare
The tuber coxae moves ventrally and laterally.
This creates tensile stress through the abdominal wall, inguinal region, and sacrosciatic ligament.
What This Actually Means
It is rarely dramatic displacement.
It is a subtle alteration in orientation and tension, just enough to:
โข Create asymmetric loading in the sacroiliac ligaments
โข Disrupt force transmission from hind limb to trunk
โข Alter proprioceptive feedback from the pelvis
โข Change neuromuscular timing
The horse does not lose strength first.
It loses clarity of position.
When the brain receives distorted mechanical input from the pelvis, it prioritises protection over performance.
Soft tissues then overwork to stabilise a torsioned frame.
This is where chronic compensation begins.
